Specification of Letters Patent.

Patented Feb. 26, 1918.

Application filed September 17, 1915. Serial No. 51,209.

To all whom it may concern:

Be it known that I, ADELARD AMYoT, a subject of the King of GreatBritain, and

residing at 590 'Valois street, Montreal,

Province of Quebec, Canada, have invented certain new and usefulImprovements in Show-Cases or Refrigerators, and do hereby declare thatthe followin is a full, clear, and exact description of t e same.

This invention relates to cases for the reception and preservation bycooling of perishable commodities and an object of the invention is toprovide an improved mode of ventilation for such cases.

Another object isto improve the construction of such cooling cases.

Another object is to provide an improved cooling case which may be usedwith or without ice.

Further objects and advantages will be hereinafter more fully describedand particularly pointed out in the appended claims.

For full comprehension, however, of my invention, reference should behad to the accompanying drawings forming a part of this specification,in which similar reference characters indicate the same parts andwherein:

Figure 1 is a perspective view of the show case employed with anice-chest;

Fig. 2 is asimilar view of the case without the ice-chest;

Fig 3 is a horizontal section on line 33 Fig. 5;

Fig. 4 is an enlarged transverse section of the upper part of thesl10wcase;

Fig. 5 is a longitudinal vertical section on line 55 Fig. 6;

Fig. 6 is a transverse vertical section on line 6-6 Fig. 5 and Fig. 7 isa detail perspective illustrating the corner constructions with theparts disconnected.

While my invention is applicable to refrigerators I have illustrated itin connection with a show case which consists preferably'of base 2,corner posts 33, 41, top frame 4, shelving 5 and rear doors 6, provisibnbeing made for the cooling of the case either by ice or by the admissionof cooled air, as will be presently described.

The front, ends and top of the cooler are double walled, the showcasehaving spaced,

sleets 7 and 8 of glass at the front and sides and spaced sheets 9 and10 of glass at the top and I have provided an improved means ofventilation for thespaces between the inner and outer walls and theinterior of the case which preferably consist of vents 11 extending fromthe interior to the exterior of the case and vents 12 and 13respectively extend ing from the spaces between the inner and outerwalls to the exterior of the case.

In the preferred form the vents 12 extend substantially horizontallyfrom the space between walls 9 and 10 outwardly to the atmospherethrough the top frame at suitable intervals around the'latter andthe'vents 11 extend from the interior of the case diagonally upwardlythrough the top frame and respectively communicate with one of the vents12 between the ends of the latter while the vents 13 extend from thespaces between walls 7 and 8 upwardly through the top frame andrespectively communicate with one of the vents 12 between the ends ofthe latter and at the junction of vents 11 and 12. In this way athree-way vent is formed at the front and ends of the case and a twowayvent at the rear so that the ascending heated or contaminated air inboth the interior of the case and between the inner and outer walls iscontinuously carried off and the full efficiency of the cool airadmitted to the case utilized for the preservation of the contents ofthe latter, the disposal or elimination of heated air being acceleratedby the'union of the different vents in that the passage of air throughone tends to create a suction in the other and so sucks the airtherethrough.

Vertically spaced supports 14 for the shelves 5 extend transverselyacross the end of the case from front to rear corner posts to which theyare secured by screws, the shelves, which are spaced from the front andrearof the case to facilitate circulation, resting loosely upon andextending between these supports and additional supports 15 screwed topairs of uprights 16 disposed toward the center of the case those ofsaid.

uprights at the rear extending between and being screwed at their endsto the base and rear portion of the top frame for which they constitutea brace to prevent sagging thereof. The front uprights 16 are spacedfrom the inner front wall and are secured at the bottom to the base 2 byscrews, the

the uprights and brace same against twisting. The lower ends of theuprights 16 are braced by pieces 17 screwed to the base and extendingtransversely of the case between the front and rear uprights of eachpair and by pieces 17 screwed to the base and extending between thefront upright and front of the case, said pairs of uprights being spacedlongitudinally of the case to provide a central space for theaccommodation of an ice-chest 18.

There are preferably three doors 6 which are slidably mounted upontracks 18 and individually of less width than the case but adapted tocollectively completely close the back of the case and may be moved toprovide an opening giving access to either end of the showcase or asshown in Fig. 3 the space between the uprights 16 so that" the ice chestmay be inserted or removed.

When the ice-chest is inserted it rests loosely upon shoulders 19presented by the braces 17 and is therefore spaced upwardly from base 2,the top of the chest being provided with a perforated cover 20 and theend spaces of the case so that with the ends of the shelves spaced fromthe front and back of the case, a thorough and complete circulationthroughout the case is secured.

The front of the ice-chest is spaced from the inner front wall of thecase, being preferably flush with the outer uprights 16 and the supports15 extend outwardly from the chest and support smaller shelves 23extending across the front of the chest, movement of the chest in aforward direction being limited by a stop24 which rests loosely uponbraces 17 and constitutes a lower shelf which with the other shelves 5and 23 can be removed.

' A water outlet 25 from the chest through the base is provided but ifit is desired to use the case without an ice-chest the latter may beremoved, in which case the outlet 25 1s plugged and chilled air admittedto the case through pipe 26'which inay lead, from the outside of abuilding opening 27 disposed about the center of base 2 and which isclosed by a plug or cap 28 when the ice-chest is utilized.

When the case is thus cooled without the aid of ice the central space isfilled in with shelves29 upheld by the supports 15, the perforatedcover20 of the ice-chest being placed upon the shoulders 19 flush withstop 24 and while serving as a lower shelf also acts as a baflle fordistributing the chilled air laterally through vents 22 as it entersthrough opening 27.

The several units of the showcase are made of standard size forconvenience of for instance to an.

renewal and are for the most part formed to strongly interlock andfastened in place by screws only so that the case can be readily takenapart and packed in a small space for transportation, the preferreddetail construction being as follows:

The base 2 of the showcase is depressed at the front and ends to receivelower frame pieces 30 screwed to the base and having the upper sideslongitudinaly grooved or stepped to form inner and outer shoulders 31and 32 respectively, the adjacent ends of the-front and end frame piecesbeing spaced from each other to accommodate front corner posts 33, theopposite sides of each of which are longitudinally grooved to form innerand outer shoulders 34 and 35 respectively, corresponding to andcontinuing upwardly from the shoulders 31 and 32. The spaced ends of thelower frame pieces are transersely grooved to form stepped projections36 fitting snugly into the grooves of the front corner posts andinterlocking the members. The lower ends of the front corner posts areeach reduced to form a shoulder 37 and a 'downwardly extendingprojection 38, the shoulders resting upon the base and the projectionsbeing set flush with the edges of the base in front corner notches 39and held in place by screws.

'The rear corners of the base are notched at 40 to accommodate the lowerreduced ends of the rear corner posts 41 which are,

flush with the edges of the base and screwed thereto, the inner side ofeach of such rear corner posts being longitudinally recessed at 42 toreceive the edges of the doors 6 and form a tight closure thereby. Thefront side of each rear corner post is longitudinally grooved or steppedto forminner and outer shoulders 43 and 44 respectively, correspondingto and extending upwardly from the shoulders of the lower end frameplace by beading 50, the outer sheet 10 resting upon the upper side ofthe top frame and being held in place by a removable strip 51 screwed tothe rear piece 52 of the frame and having an undercut portion for thereception of the rear edge of sheet 10 which latter and sheet 9 can thusbe readily removed from the outside merely by loosening the strip 51 andbeading 50.

The top frame includes front and end pieces 4, the lower sides of whichare longisecured together by screws, the outer cor-- 11ers so formedresting upon and being screwed to the front corner posts which areinwardly stepped as at 56 to accommodat the shoulders 53 and 5 Theunderside of the rear piece 52 of the top frame is longitudinallyrecessed at 57 f0 loosely receive and guide the tops of certain of thedoors 6, the others being guided by a retaining strip 58 screwed to theback of the rear'piece 5 2.

The opposite ends of the rear piece 52 rest upon the rear corner postsand are each undercut to form a shoulder 57 abutting against the innerside of the adjacent post, the upper side of the ends of the rear piecebeing depressed at 58 to receive the projecting ends 59 of the' endpieces 4 of the top frame which are undercut to form shoulders 60 and 61respectively abutting against the rear piece52 and rear corner posts 41,the several members so interlocked being secured by screws which extenddown through the frame pieces 52 and 4 into the corner posts.

Owing to the overlapping or interlocking joints a showcase of the abovedescription is particularly suited to act as a receptacle for thepreservation of perishable commodities and in view of the facility withwhich the parts of said case can be, disconnected, it can be readilytaken apart and compactly packed for transportation and again as sembledwith a minimum amount of labor.
